The Boston Celtics have kept their season going at least another game.

But their job isn't done yet.

The Celtics need to beat the Knicks in Game 6 in Boston on Friday night to force the series to a decisive seventh game. The Celtics are hoping to become the first team in NBA history to advance after losing the first three games of a best-of-seven series.

Celtics center Kevin Garnett says it's not time for the team to relax. Their goal wasn't to extend the series, it's to win it.
